Shell Programming and Scripting

Hi,

I am using the below command to find out the mail logs which will grep the repeated message ids:

Code:

less /var/log/messages  |awk '{print +$6}'| sort | uniq -c | sort -nr

OUTPUT:

Code:

    506 1246382279
    404 1246373467
    303 1246383457
    303 1246382268
    300 1246379705
    202 1246383452
    202 1246383448
    202 1246382281
    201 1246383456
    201 1246382284
    201 1246379685
    201 1246374656
    200 1246383453

I am trying to get this to be emailed when if the counts exceeds more than 100 via shell script implementing through cron . but I am not good in shell scripting. can you please advice me on this.

try:

Code:

count=$(/var/log/messages |awk '{print +$6}'| sort | uniq -c | sort -nr | wc -l)
if [ $count -ge 100 ];then
echo "some body" | mailx -s "WARNING:: Message" "someone@somewhere.com" 2> /dev/null
fi

Hi anchal,

Thank you for your reply.

Let me be more specific on my query.

Under my /var/log/message, the output will be like

Jun 30 09:53:30 server-27 in[28989]: 1246373453|jason@abc.com|djstaffo@yahoo.com|2227|success|1
Jun 30 09:53:31 server-27 in[28989]: 1246373453|jason@abc.com|djstuder@yahoo.com|2227|success|1
Jun 30 09:53:33 server-27 in[28989]: 1246373453|jason@abc.com|djsussma@oakland.edu.uk|2227|success|1
Jun 30 09:53:34 server-27 in[28989]: 1246373453|jason@abc.com|djt1000@aol.com|2227|success|1
Jun 30 09:53:35 server-27 in[28989]: 1246373453|jason@abc.com|djtc7109@aol.com|2227|success|1
Jun 30 09:53:36 server-27 in[28989]: 1246373453|jason@abc.com|djuba9@aol.com|2227|success|1

So, what I am doing is,by using the command, (less /var/log/messages |awk '{print +$6}'| sort | uniq -c | sort -nr), it will give me the ouput as

506 1246373453
404 1246373467
303 1246383457
303 1246382268
300 1246379705

Where:
1246373453 -> 1246373453|jason@abc.com|djstaffo@yahoo.com|2227|success|1

So, the picture of my outcome should be like the output should be redirected to the file and that file should verify the count , if the count exceeds more than of 100, it should send me an email.
I hope it make sense.

Are you sure you are getting this output:

Code:

506 1246373453
404 1246373467
303 1246383457
303 1246382268
300 1246379705

I get this..

Code:

   1 1246373453|jason@abc.com|djuba9@aol.com|2227|success|1
   1 1246373453|jason@abc.com|djtc7109@aol.com|2227|success|1
   1 1246373453|jason@abc.com|djt1000@aol.com|2227|success|1
   1 1246373453|jason@abc.com|djsussma@oakland.edu.uk|2227|success|1
   1 1246373453|jason@abc.com|djstuder@yahoo.com|2227|success|1
   1 1246373453|jason@abc.com|djstaffo@yahoo.com|2227|success|1

No, I got only the count and not the email. Okay that not an issue. I am trying with redirecting the output to a file and the file should count which has to be done via shell script. Please help me on this ...

Ok
redirect this output to a file
output > new_File
for counting did you mean the first field greater than 100?

yes, it should be greater than 100...
